Key result
High self-reported stress is linked to lower HRV coherence scores among female assembly-line workers.
Why the study?
The correlation between self-reported stress and heart rate variability as a physiological marker among assembly-line workers was not well established.
Does self-reported stress correlate with heart rate variability in assembly-line workers?
Cross-Sectional (n=36)
Does self-reported stress correlate with heart rate variability in assembly-line workers?
Objective HRV physiological evaluations correlate with self-reported stress measures, suggesting they can be integrated to assess stress states.

Supports combining HRV coherence with self-reports for stress assessment in female workers; hypothesis-generating and needs prospective validation before wider use.
The main objectives of this study were first to evaluate a correlation between self-reported stress and heart rate variability (HRV) as a physiological marker, and secondly to examine the HRV difference between high and low-stress level workers. The participants consisted of 36 assembly-line female workers who were divided equally into a high (HS) and low-stress group (LS). The HS group consisted of subjects who reported extremely severe of depression, anxiety, stress, scale (DASS) measures while the LS participants were randomly selected from the 99 participants who had normal to moderate levels of each scale of DASS. All participants attended one session HRV measurement. Pearson correlation coefficients showed negative associations between DASS and the HRV coherence scores as well as differences on HRV between two groups. These findings suggested that objective HRV physiological evaluations and self-reporting measures may be integrated when assessing stress to capture a well-rounded picture of participant's states.

Khairi et al. (2020) conducted a cross-sectional in Stress (n=36). High self-reported stress vs. Low self-reported stress was evaluated on Heart rate variability (HRV) coherence scores. High self-reported stress was negatively associated with heart rate variability coherence scores compared to low stress among female assembly-line workers.
